My sister undergone radiation in 2007 for suprasellar germinoma. Her periods stopped in 2006. From then no periods after radiation also. From past 4 years she is behaving abnormally like talking to herself, not sleeping in nights, arguing for small issues, calling us with different names. There is no problem with her memory. Like she is suffering psychologically. Before 2006 she was good & normal. Now We are taking care of her like a baby. But year by year problem is worsening. With these health issues she remained unmarried. Is there any solution for my sister to become normal?
